Size-dependent mechanical properties of molybdenum nanopillars

We report the deformation behavior of single crystalline molybdenum nanopillars in uniaxial compression, which exhibits a strong size effect called the “smaller is stronger” phenomenon. We show that higher strengths arise from the increase in the yield strength rather than through postyield strain hardening. We find the yield strength at nanoscale to depend strongly on sample size and not on the initial dislocation density, a finding strikingly different from that of the bulk metal

Queer Survival Amidst HIV/AIDS, COVID-19 and Homelessness

The treatment and survival of a society\u27s marginalized peoples reveal the true impacts of a pandemic. An analysis of homeless queer youth during the HIV/AIDS and SARS-CoV-2 crises lays bare the systemic failure of the United States government to provide equitable healthcare. I compare the HIV/AIDS and COVID-19 pandemics in queer homeless youth to demonstrate the dangers of disease moralization via a sociocultural analyses of disease stigma and responsibility politics. Utilizing syndemic theory I draw on the synergistic relationship between disease and illness to describe the unique challenges queer homeless youth face. A syndemic framework is applied to address common comorbidities that exist in queer homeless youth populations, with a focus on socio-cultural phenomena that rendered queer youth susceptible and vulnerable to homeless, HIV/AIDS, COVID-19, drug and alcohol abuse, mental health struggles, and tobacco use. Understanding how and why queer homeless youth become ill lays the foundation for how disease moralization impacts resource and healthcare accessibility. The social construction of HIV/AIDS aided in the creation of the at-risk identity whereby all queer peoples are understood to be at risk for HIV, and thus queerness itself becomes a risk factor. The at-risk identity and the moralization of HIV creates a sense of deservedness; i.e. queer people deserve their diagnosis, suffering and death due to their engagement in risky behavior. Key risk behaviors include anal and vaginal sex and intravenous drug usage. Understandings of consent and survival further frame how queer homeless youth are impacted. The at-risk identity and conception of deservedness may be compared to COVID-19. Queer homeless youth engage in many COVID-19 risky behaviors, such as not socially distancing, which leads to a social conception of deserving their illness and the suffering that comes with it. These existing crises have amplified the impact of an unjust healthcare system

The Role of Financial Aid Counseling in Students\u27 Understanding of Student Loan Management.

This exploratory research study examined public university students\u27 perceptions about their own loan debt management knowledge and about the counseling practices used to prepare them for their loan responsibilities. From the target population of all students enrolled at Louisiana State University during the Spring 1999 Semester, a systematic random sample was selected. Of the 1,204 students who participated in the study, 433 had loans. The 34-question survey instrument included 11 demographic characteristic questions and 1 open-ended question asked of all respondents. Two additional demographic questions and 20 perception statements about the loan process were asked of loan recipients. This study found that many students do not understand their loan obligations, that they received inadequate counseling about financial aid at both the high school and college levels, and that some students are accumulating additional college debt through the use of credit cards. Three factors were identified through factor analyses as underlying constructs in the 20 perception items: Students\u27 perceived knowledge of the loan process, Students\u27 decision to use loans, and Students\u27 source of loan knowledge. Multiple regression analysis showed that each of the factor models was significant. Factor 1, Students\u27 perceived knowledge of the loan process, explained 22.2% of the variance in students\u27 understanding of their loan responsibilities. Three variables contributed significantly to this model: the student not knowing what type of loan they had, the total number of semesters enrolled in college, and whether or not the student was white. A loan recipient model was identified through discriminant analyses that correctly classified 74% of the cases analyzed. Significant variables identified in this model were: (1) whether or not student received a financial aid grant, (2) 1998 family income, (3) whether or not student received financial aid work study, (4) amount of scholarship(s) received, (5) parent\u27s highest level of education, (6) status in college, (7) whether or not black, (8) number of semesters enrolled in school, (9) whether or not white, (10) whether or not student received a scholarship, (11) whether or not student used a credit card to help pay college expenses

Korean Scholars’ Use of For-Pay Editors and Perceptions of Ethicality

Many Korean scholars rely on language professionals for preparing English manuscripts. So far, little has been reported on how Korean scholars utilize them and how they perceive various types of help received. This study examines how Korean scholars utilize for-pay editors and translators, and how they perceive various types of textual modifications incurred in the process, based on the data obtained through a survey completed by 88 Korean faculty from three universities. Half of the participants received proofreading help from for-pay editors, and fewer participants received help with translation. They held widely differing views on ethicality concerning scenarios that involved global- and content-level editing; none of the help described was perceived as clearly unethical. This paper argues that as the academic communities benefit from the knowledge and insights created through research conducted by scholars across the world, it is necessary to establish proper boundaries of writing help

How Does Focus on Form Affect the Revising Processes of ESL Writers?: Two Case Studies

This study considers the ongoing “grammar correction debate” in second language writing by examining how a focus on formal accuracy would affect the revising processes of ESL writers and the students’ written products. A case study approach was used to find out how two ESL students would respond in the two different rewriting situations: (a) when there is no explicit expectation for them to produce grammatically correct text, and (b) when this expectation was clearly present. The protocol analysis and interviews with the participants showed that students’ revision processes had not been affected by the kind of instruction and expectation given. In both tasks, students concentrated on building up their content, rather than attending to grammar and mechanics. The explicit instruction to work on the grammar did not result in a better written product in terms of formal accuracy, either. Based on these findings, this study claims that teaching and attending to grammar may not necessarily inhibit students from developing fluency and that ESL students do need guidance in developing skills in both rhetorical and formal aspects of English composition to be able to produce academically acceptable prose

Scholarly Publishing in Korea: Language, Perception, Practice of Korean University Faculty

This study reports how internationalization of academic knowledge is reflected in the language choice of Korean academic journals across disciplines and examines perceptions and practices of eighty two faculty from various disciplines at three Korean universities concerning publishing in English journals. The results indicate that natural science has the highest percentage of English-medium journals whereas those in humanities and social science predominantly use Korean as a medium of publication. Similar disciplinary patterns are observed in the responses to survey questions about frequency of publication as well as desire and preference for publishing papers in English. The biggest motivation for Korean scholars to publish in English was the desire to reach global scholarly communities. Implications of these findings are discussed

Perceptions of landscape function within the field of landscape architecture

textLandscape functions are the processes that support life by rendering ecosystem services and goods. Thus, in a time of profound ecological destabilization, our future well-being depends on our ability to preserve, to enhance, and to avoid degrading landscape functions. Landscape architects have the opportunity to play a significant role in this project, but they cannot design for (or around) that which they do not perceive. Using an interpretive approach, and a sample of Texas landscape architects, this research explores which landscape functions this group of professionals readily perceives and various understandings of the concept of landscape function within the field. Participant authored photography, a written-answer questionnaire, and a photographic observation activity resulted in 539 functions that were coded and categorized using a modified grounded theory approach. Findings from this sample of landscape architects indicate a strong focus on functions related to the human user and to site use and reveal various understandings of landscape function.Architectur

Born Again with Trump: The Portrayal of Evangelicals in the Media

Since Trump’s ascendancy in American politics and his subsequent election, a number of articles have surfaced in the media trying to explain evangelical voters’ support of Trump. This paper analyzes common descriptions and conceptions of evangelicals by identifying recurring descriptions of evangelicals in 110 online articles published in a two-and-a-half-year period surrounding Trump’s presidential campaign and election. The results indicate that the answer to the question as to why evangelicals support Trump resides not so much in their theology, but in their aspirations for America and assumptions of what America should be like. This paper argues that it is crucial to recognize and address evangelicals’ prevailing attributes as perceived and portrayed by members of their own society in order to keep evangelicalism from descending into an insular, invalid expression
